This reverts commit 0abbfab320.
Reason for revert: Changelog was based on rc0 tag but we got few more patches after that which were not captured.

With SPMC at el3 enabled on rdn2cfg2 configuration BL31 needs more
memory region to accommodate increased xlat table size.
Increase the size by 16K.

Arm has made the strategic decision to deprecate the TC1 platform.
Consequently, software development and the creation of fast models
for the TC1 platform have been officially discontinued.
The TC1 platform, now considered obsolete, has been succeeded by
the TC2 platform. It's noteworthy that the TC2 platform is already
integrated and supported in both TF-A and CI repositories.

A number of features are marked experimental in the build system through
makefiles but there wasn't an explicit document to list them.
Added a dedicated experimental build options section and moved
existing experimental build option descriptions in this section.
Restoring the change from [1] removing the experimental flag on the EL3
SPMC (this has been lost in rebasing a later change).

Currently MediaTek platform code does not support the bl32 image.
Remove bl32 support from Makefile to prevent the build failure when
NEED_BL32 build flag is enabled.

This change updates the model versions that we claim to be testing with
to reflect what the reality in the CI.

We have to handle wide selection of cpu cores in one TF-A binary:
- v8.0: a53, a57, a72
- v8.2: a55, a76, n1
- v8.4: v1
- v9.0: a710, n2
And then we have QEMU's hybrid: 'max' which has everything QEMU can
emulate.
TF-A for QEMU platforms was built for v8.5 architecture. But turned out
that 'max' has v8.7 flag now (HCX) which we need to have. And this
enabled set of mandatory features which made TF-A not-bootable on
v8.0/8.2 cpus.
So I decided to follow Arm FVP way and do build for v8.0 with set of
feature flags enabled. This way we have bare minimum to make v8.0 cpus
boot. And then all features from newer cores are enabled with runtime
check which makes them boot.
Tested with BSA/SBSA ACS and Debian Linux 6.5 kernel.

Arm Confidential Compute Architecture (Arm CCA) support, underpinned by
Arm Realm Management Extension (RME) support, brings in a few important
software and hardware architectural changes in TF-A, which warrants a
new security analysis of the code base. Results of this analysis are
captured in a new threat model document, provided in this patch.
The main changes introduced in TF-A to support Arm CCA / RME are:
- Presence of a new threat agent: realm world clients.
- Availability of Arm CCA Hardware Enforced Security (HES) to support
measured boot and trusted boot.
- Configuration of the Granule Protection Tables (GPT) for
inter-world memory protection.
This is only an initial version of the threat model and we expect to
enrich it in the future.

Removed RSS usage from the Base AEM FVP platform, as it wasn't
functional on this platform. The Base AEM FVP platform lacks
support for RSS.
Instead, the TC2 platform with RSS is available for actual RSS
interface implementation and testing.

Removed the PLAT_RSS_NOT_SUPPORTED build option, which was initially
introduced for building the Base AEM FVP platform platform with RSS.
However, we now have a well-defined TC2 platform with RSS, making it
unnecessary to keep this flag.
Note -
Theoretically this is a breaking change. Other platforms could be
using the PLAT_RSS_NOT_SUPPORTED build option. Among upstream platforms,
only the Base AEM FVP uses it right now but we don't know about
downstream platforms.

The usage of this macro hinders the accuracy of code coverage
data. Lines of code calling this macro always appear as covered because
the test condition within it always gets executed; however, the branch
is not necessarily taken. Consequently, we lose branch coverage
information on these error code paths.
Besides, it is debatable whether such a simple macro really improves
code readability or on the contrary obfuscates the code...
For these reasons, this patch inlines the macro code everywhere it was
called.
It also adds some error messages in all these places to help narrowing
down authentication failures. These messages only get displayed and
compiled into the binaries when building TF-A with 'LOG_VERBOSE' level
of verbosity. We use the same message string everywhere in order to
limit the memory footprint increase for 'LOG_VERBOSE' builds.

TF-A supports reading input data from UART interfaces. This opens up
an attack vector for arbitrary data to be injected into TF-A, which is
not covered in the threat model right now.
Fill this gap by:
- Updating the data flow diagrams. Data may flow from the UART into
TF-A (and not only the other way around).
- Documenting the threats inherent to reading untrusted data from a
UART.

Both qemu and qemu-sbsa use xlat tables v2 already (activated by including it
in common/common.mk) so there is no need to include compat headers.

Addressed the SPMC_AT_EL3 condition by using '#if' instead of
'#if defined'. This change is warranted because the SPMC_AT_EL3
option is always defined.

CryptoCell-712 and CryptoCell-713 drivers have been deprecated since
TF-A v2.9 and their removal was announced for TF-A v2.10 release.
See [1].
As the release is approaching, this patch deletes these drivers' code as
well as all references to them in the documentation and Arm platforms
code (Nuvoton platform is taken care in a subsequent patch). Associated
build options (ARM_CRYPTOCELL_INTEG and PLAT_CRYPTOCELL_BASE) have also
been removed and thus will have no effect if defined.
This is a breaking change for downstream platforms which use these
drivers.

Note that TF-A v3.0 release later got renumbered into v2.10.
